I would say AAPL needs to break 520 (upside gap) to turn in a reversal otherwise we hold 512 support area or move lower.
Not Apple related but when trading now also consider that market is very weak and you should expect sell off soon. Leading economical news like consumer sentiment, retail sales, CPI, all will be negative. Market indicates a sell while we have an up day as of now. ES Dec is 1426 as of now but I expect market to close red.
You didn't update your chart, but I'm going to step in here... Engulfing candle with pretty solid volume on the day means that if you have an aggressive trading style, you can "cheat" here with an earlier entry. Can get better prices without having to wait for the gap to fill.
